AI Technical Summary

Benefits of technology

The present invention solves two technical problems. Firstly, it allows for a compact and easy-to-use foldable pinwheel that can be quickly mounted and unfolded. Secondly, it reduces the overall volume during transportation or storage by locking the rotary blades.

Problems solved by technology

In other words, when in sale, pinwheel blade assemblies and other components have been fixedly mounted and cannot be disassembled for reassembly.
For some pinwheels, although the stand and the pinwheel blade assemblies can be combined, the pinwheel blade assemblies that occupy most of the space still cannot be disassembled and then reassembled.
As a result, the pinwheel blades are often damaged during transportation and in sale, or users discard pinwheels at will or are less willing to buy pinwheels due to the inconvenience for storage.
Here, the blades cannot be detached or folded during storage or transportation, and thus it is relatively troublesome.

embodiment 1

[0033

[0034]As shown in FIGS. 1, FIGS. 2 and FIGS. 3, the foldable pinwheel in this embodiment comprises a central pole 1 and a blade assembly rotatably disposed on the central pole 1. The blade assembly comprises a plurality of helical rotary blades 2 and two locking mechanisms 4 rotatably disposed at two ends of the central pole. Two ends of each rotary blades 2 can respectively be secured with the corresponding locking mechanism 4. The rotary blades 2 can be folded together when the locking mechanisms 4 are all in an unlocked state. the plurality of rotary blades 2 can be stacked up together when the locking mechanism 4 is in an unlocked state, and the locking mechanism 4 can secure the plurality of rotary blades 2 in a stacked up position.

[0035]The locking mechanism 4 at the upper end comprises a base 41, a locking sleeve 42 and a locking lid 43. The base 41 is rotatably disposed on the central pole 1 and has a support 411 running through one end of the rotary blade 2. A rotatabl...

embodiment 2

[0046

[0047]As shown in FIG. 7, in this embodiment, a holder 7 is provided on the central pole 1 below the blade assembly, and an illuminator 72 that emits light upward and a solar panel 71 that supplies power to the illuminator 72 are arranged on the holder 7. Here, the solar panel can be replaced with an accumulator. However, when considered from environmental protection, the solar panel is preferred. Please refer to Embodiment 1 for other structures.

embodiment 3

[0048

[0049]As shown in FIGS. 8 and 9, in this embodiment, the central pole 1 comprises a horizontal pole 1a and a vertical pole 1b. The horizontal pole 1a is arranged on the top of the vertical pole 1b. Two blade assemblies and respective locking mechanisms 4 are arranged at two ends of the horizontal pole 1 a. Each of the rotary blades 2 is platy. Please refer to the arrangement shown in Embodiment 1 for the locking mechanisms 4.

Abstract

The present invention discloses a foldable pinwheel, which comprises a central pole (1); and a blade assembly rotatably disposed on the central pole (1); the blade assembly comprises a plurality of rotary blades (2) and at least one locking mechanism (4), which is rotatably disposed on the central pole (1); the plurality of rotary blades (2) can be stacked up together when the locking mechanism (4) is in an unlocked state, and the locking mechanism (4) can secure the plurality of rotary blades (2) in a stacked up position. The folding and unfolding of rotary blades are realized by a locking mechanism. The overall volume can be effectively reduced during transportation or storage. When in use, the pinwheel can be mounted quickly. It is convenient and fast.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of priority to CN 201811607888.X, filed on Dec. 27, 2018, the entire specification of which is hereby incorporated by reference.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates to a wind-driven device, and in particular to a foldable pinwheel.BACKGROUND OF THE INVENTION[0003]Most commercially available pinwheels are constructed integrally. In other words, when in sale, pinwheel blade assemblies and other components have been fixedly mounted and cannot be disassembled for reassembly. For some pinwheels, although the stand and the pinwheel blade assemblies can be combined, the pinwheel blade assemblies that occupy most of the space still cannot be disassembled and then reassembled. As a result, the pinwheel blades are often damaged during transportation and in sale, or users discard pinwheels at will or are less willing to buy pinwheels due to the inconvenience for storage.[0004]The pres...
